An Enhanced Arabic OCR Degraded Text Retrieval Model
نویسندگان
چکیده
This paper provides a new model enhancing the Arabic OCR degraded text retrieval effectiveness. The proposed model based on simulating the Arabic OCR recognition mistakes on a word based approach. Then the model expands the user search query using the expected OCR errors. The resulting expanded search query gives higher precision and recall in searching Arabic OCR-Degraded text rather than the original query. The proposed new model showed a significant increase in the degraded text retrieval effectiveness over the previous models. The retrieval effectiveness of the new model is %97, while the best effectiveness published for word based approach was %84 and the best effectiveness for character based approach was %56. In addition, the new model overcomes several limitations of the current two existing models.

متن کاملFusion of Multiple Corrupted Transmissions and its effect on Information Retrieval
Much previous work has focused on correction of OCR degraded text with little work addressing the possibility of fusing the generated text from different OCR systems, which are assumed to produce different types of errors. This paper explores text fusion, which involves the use of language modeling to determine which OCR system (if any) properly recognized individual words. The technique was ap...

متن کاملQuery Translation and Expansion for Searching Normal and OCR-Degraded Arabic Text
This paper provides a novel model for English/Arabic Query Translation to search Arabic text, and then expands the Arabic query to handle Arabic OCR-Degraded Text. This includes detection and translation of word collocations, translating single words, transliterating names, and disambiguating translation and transliteration through different approaches. It also expands the query with the expect...
متن کاملLength Normalization in Degraded Text Collections
Optical character recognition (OCR) is the most commonly used technique to convert printed material into electronic form. Using OCR, large repositories of machine readable text can be created in a short time. An information retrieval system can then be used to search through large information bases thus created. Many information retrieval systems use sophisticated term weighting functions to im...
